And next tonight, inside a moment of crisis. The dramatic moment of a construction worker hanging with just seconds to spare. Tonight, what was happening at the top of that ladder. Here's gio Benitez. Reporter: Curtis found himself trapped inside an inferno. I just said, god, you got to help me here. Reporter: He crawled out on to a balcony. I looked and saw the flames right there. Reporter: Five stories up, and the fire is getting closer and close. Let's pause the video for a moment. This is where he thought there was absolutely nowhere to go. Then he had an idea. The only choice, drop down below. That was the only option. Reporter: He's swinging, and watch. Oh, no. Oh, no. Reporter: He lands on the balcony. That's when the fire captain swings in on his ladder. The ladder was about two feet short of the patio. So, Curtis had to jump again. Hell yes. He said, hang on. I said, I am. Let's go. Reporter: They went, and within seconds, the moment that would put everyone in danger. Oh, no. Reporter: Tonight, he and his wife call that fire fighter a real hero. Alive, and tonight, going right back to work. Gio Benitez, ABC news, New York.
